Auto-fetched favicons and user uploads shared one icon_b64 column, so
"Clear cache" wiped custom uploads and "Re-fetch all" overwrote them — data
loss the user can't undo (a custom icon exists precisely because DDG can't
fetch that site).
New icon_custom flag (0=fetched cache, 1=user upload). Invariant: an
automatic action never touches a custom icon; only the user changes/removes
it per entry.
- Schema: icon_custom INTEGER on vault_entries.
- POST /entries/{id}/icon takes {custom}; GET /entries echoes icon_custom;
DELETE /entries/icons/all filters COALESCE(icon_custom,0)=0.
- saveEntryIcon(id, uri, isCustom): upload→true, fetch/remove→false.
- backfillFavicons skips icon_custom even on force (Re-fetch all).
- clearAllFavicons clears only non-custom locally + refreshes the open editor
(the icon preview didn't update on clear before).
- duplicate re-stamps a copied custom icon; import-overwrite carries the flag.
Not propagated across bulk-import / sync (the bulk INSERT doesn't read it) —
a restored icon counts as fetched. Documented; custom icons are typically
self-hosted sites DDG won't re-fetch anyway.
